Highest Damage against Dialga in the story

Hey everyone i would like to know about the hardest hit you have done against Dialga to stop time from being destroyed

please also list the items, I.Q.skills that affect stats,Pokemon used, move used, and level at the time and if you used golden seeds to hit that level also I really would prefer the hit being done WITHOUT AN ACTION REPLAY PLEASE

I was also a Riolu, But my lvl was WAY lower than yours;
Riolu
lvl 35
Move; Force Palm
Damage; 311
IQ; Don't know XD
Items Used; Sleep Seed. And this is (i think) hard to believe, but i did't use ANY reviver seeds :D
